Home Healthcare Training System

My Role/Contribution:

- Designed and coded the hint system within a Virtual Simulation Training Program (using Unity and C#) which was developed to train home healthcare professionals.
- Carried out formative usability testing for the hint system and improved the features.

Introduction of the training system

https://homehealthcaresafety.osu.edu/

Phase I:

Develop a Virtual Simulation Training System (VSTS), using an interdisciplinary, participatory design approach.

Questionnaire
8 focus groups, 37 interviews
Participants' room drawing

Transcript analysis to learn about

Types of hazards
Room of hazard

System Development:

Program: Unity + C#
Hazard information: Excel spreadsheet

Phase II:

Assess the usability, usefulness, and desirability of the VSTS across multiple professional disciplines.

Usability Evaluation Result:

Easy to use (88%)
Easy to move around (75%)
Easy to click on hazards (63%)
Not hard to see hazards (75%)
Dialog boxes easy to click thru (100%)

... ...

Took too long to finish (25%)

Potential Solution:

Hints that guide the users to the rest of the hazardous objects

Designed the hint system

Text + Audio alert
Time point of hint delivery

Program coding

Interface development

Usability Testing

• Hints are triggered at the right time point

• Hints catch the user attention

• Hints direct the user to the right object

• Hints show up/turned off as needed

Phase III (Ongoing):

Evaluate the efficacy of the VSTS in preparing home healthcare professionals to recognize, assess, and respond to hazards in the home health environment using appropriate risk perception and decision-making processes
